As for Virginia...
It looks like a 4 plant limit for home cultivation with 2 mature plants and 2 immature plants. I'm interpreting that as meaning 2 in flower and 2 in veg at any given time. Some states that have legalized recreational don't allow home cultivation. Any decent grower can keep themselves supplied with that limit.
§ 4.1-1101. Home cultivation of marijuana for personal use; penalties.
A. A person 21 years of age or older may cultivate up to two mature marijuana plants and two immature
marijuana plants for personal use at their place of residence; however, at no point shall a household contain
more than two mature marijuana plants and two immature marijuana plants. For purposes of this section, a
"household" means those individuals, whether related or not, who live in the same house or other place of
residence.
A person may only cultivate marijuana plants pursuant to this section at such person's main place of
residence.
B. A person who cultivates marijuana for personal use pursuant to this section shall:
1. Ensure that the marijuana is not visible from a public way without the use of aircraft, binoculars, or
other optical aids;
2. Take precautions to prevent unauthorized access by persons younger than 21 years of age; and
3. Attach to each mature marijuana plant and immature marijuana plant a legible tag that includes the
person's name, driver's license or identification number, and a notation that the marijuana plant is being grown
for personal use as authorized under this section.
C. A person shall not manufacture marijuana concentrate from home-cultivated marijuana. The owner of
a property or parcel or tract of land may not intentionally or knowingly allow another person to manufacture
marijuana concentrate from home-cultivated marijuana within or on that property or land.
D. The following penalties or punishments shall be imposed on any person convicted of a violation of this
section:
SB1406S1 157 of 263
